useful Improvements in Explosive-Engines,

and I do declare the following to be a f ull,clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in explosive-engines and has particular reference to the means for and manner of admitting the liquid fuelsuch, for example, as gasolene and air-to the vaporizing-chamber.

The object of the invention is to obtain a uniform speed of the engine when using a liquid fuel regardless of the load. A constant supply of gasolene or liquid fuel is made to' pass through a vaporizing-chamber in a constant body or volume sufficient to supply a proper mixture for a maximum load. In other words, the volume of gasolene which passes through the vaporizing-chamber is sufficient to supply fuel to the engine under the heaviest load at which the said engine is run.

Preceding a detail description of my in vention reference is made to the accompanying drawings, of which- Figure 1 is a side elevation of an explosiveengine having my invention applied thereto. Fig. 2 is an enlarged sectional elevation of the casing which incloses the vaporizing and valve chamber. Fig. 3 is a section on the line 3 3 of Fig. 2.

In a detail description of the invention similar reference characters indicate corresponding parts.

1 designates the power-cylinder of the engine, mounted in the usual manner in a base 7 and provided with a valve-chest 2.

3 designates a casing which provides a vaporizing-chamber 3 and is connected with the valve-chest 2 by a mixture-feed pipe 13.

8 is an air-pipe which is connected with the takes up a necessary amount thereof to providea suitable explosive mixture or vapor for the engine. The liquid fuel and the air entering the chamber 3 through the pipes 11 and S may or may not be heated prior to their discharge into said chamber. The gasolene or liquid fuel passing into the vaporizing- 7o chamber 3 falls into a lower chamber 3, constituting a liquid receiving and outlet trap, and thence it enters an outlet-pipe 9, connected totank 4, and through which it is conducted back to said receiver or tank. be seen that there is a constant circulation of gasolene or liquid fuel while the engine is in operation, and the amount that is necessary to commingle with the air in order to make a proper mixture is taken up and the remain- 8o ing portion of the gasolene is returned to the tank. In the forward portion of the casing 3 there is located a rotary mixture-throttlingvalve 20, which has a series of ports 24:. This valve is in the form of a sleeve, Which is in closed within the stationary cylinder 21, constituting a valve-casing and having a series of ports 25, with which the ports 24: may or may not register, according to the position of the valve 20. The upper side of the casing 3 0 is provided with a nozzle 26, into which is tapped the pipe 13, that communicates with the valve-chest 2, as before stated.

17 designates a cap which incloses the outer end of the casing 3 and which provides a bearing for a pin 19, the inner end of said pin 19 being connected to the mixturethrottling valve 20 at 18 and the outer. end of said pin having fixed thereto a head 14, which connects with a rod or pitman 15. This pitman 10o It willthus 75 is actuated by the governor 6 to open or close the valve 20, according to the speed of the engine. The upper end of the pitman 15 has a pivotal connection with the lever 16, which lever has a'fulcrum at 27 and is movable by the governor in a Well-known manner.

It will be understood that the admission of gas and air is controlled by the valve and that the said valve is controlled by the governor. It therefore follows that when the ports 24 register with the ports 25 in the outer valvecasing 21 explosive mixture will be generated within the chamber 3 by the air through pipe 8 coming, as before stated, in contact with the constant jet of gasolene or liquid fuel which passes through pipes 12 and 11 adjacent to the discharge end of the airpipe 8.

While I have describedin connection with my invention a rotary valve for admitting the explosive mixture to the engine, I do not Wish to limit myself to this exact form of valve, as any of the various forms of valves may be used. The essence of my invention consists in passing constantly to and from a receiver or tank a suitable volume of fuelsuch, for example, as gasolene-and in exposing the stream or volume of gasolene in a chamber to a suitable body or current of air which takes up a certain percentage of the liquid to produce a suitable vapor, and the remaining portion of the liquid or gasolene is caused to flow back to the receiver. The mixture generated in this manner produces a uniform speed of, the engine regardless of the load it is carrying, and this for electric lighting, as well as other purposes, is well known to be of much importance.

Having described my invention, I claim- 1. In an explosive-engine, the combination with the mixture-feed pipe for the engine, of

a vaporizing-chamber having at the bottom a liquid receiving and outlet trap, and at one side above the plane of said trap a horizontally-offsetported valve-casing in communication with the mixture-feed pipe, a controlling-valve arranged Within said casing, an oil-feed pipe pendent vertically within the vaporizing-chamber from the top thereof and delivering into the bottom receiving and outlet trap, and an air-induction pipe in communication with the vaporizing-chamber at one side thereof and in the horizontal plane of the ported valve-casing, said air-induction .pipe deliveringa supply of airinto the vaporizing-chamber and across the stream of oil falling into said trap, substantially as set forth.

2. In an explosive-engine, the combination with the mixture-feed pipe for the engine, of a vaporizing-chamber having at the bottom a liquid receiving and outlet trap and at one side a horizontally-ofiset cylindrical valvecasing having a ported portion in communication with the mixture-feed pipe, a horizontal tubular ported controlling-valve fitting within the cylindrical valve-casing and having its open end communicating directly with the vaporizing-chamber, an oil-feed pipe pendent within the vaporizing-chamber from the top thereof and discharging into said trap, and an air-induction pipe communicating through one side of the vaporizing-chamber in the horizontal plane of the tubular valve and at right angles to the plane of the oilfeed pipe.

In testimony whereof I affix my signature in presence of two Witnesses.
